Tämnarens FVOF is a fishing lake belonging to the municipality of Heby and Tierp, located in Uppsala County. The lake Tämnaren is a relatively shallow lake with an average depth of about 100-130 cm. The lake, however, is fish-rich and offers fishing mainly of goose, pike and perch.
Winter fishing is the time that attracts most fishermen, but time without ice works well but best if you have access to a boat.
During the summer months, it may sometimes be very low in water due to the low precipitation. This means that fishing with predominantly throwing pole will be complicated. It is recommended to check the water level conditions before the fishing license is resolved.
Annually, some fish competitions are held.
Tämnarens Fiske Vårds Områdesförening utgörs av markägare runt Tämnaren som har del i fisket i sjön. Syftet är att erbjuda möjlighet att fiska för allmänheten under kontrollerade former. Föreningen säljer fiskekort och sätter upp fiskeregler som har till syfte att bibehålla sjöns fiskbestånd på en bra nivå.
